IMPROVEMENT IN COMBINATION-LOCKS.

Specification forming part of Letters Patent No. 153,501, dated July 28,1874; application filed March 14, 1874.

To all whom it may concern:

Be it known that I, ANTHONY M. SMITH,of Brooklyn, in the county of Kingsand State of New York, have invented an Improvement in Toy Safes, ofwhich the followingis a specification:

This toy safe is intended for a money-box for children and 'others, andthe improvement relates to the means for fastening the door of the safe.

Heretofore safe-locks have been made of a bolt and circular tumblershaving notches, and set by a handle and dial, and the bolt has beenwithdrawn by turning a handle.

In my toy safe there are circular notched tumblers, combined with a boltthat has a thumb-piece projecting through a slot in the door, and thereis a spring that applies friction to the tumblers to hold them in place,and said spring serves also to project the bolt. This toy-safe lock isreliable for the usual purposes of a money-box or toy bank, and is cheapand simple, but is Wholly unavailable as a bank or vault lock, whetherof a large or small size, because the bolt itself is accessible.

In the drawing, Figure 1 is a vertical section of the toy safe throughthe center of the tumblers. Fig. 2 is a sectional plan of the lock anddoor, and Fig. 3 represents the parts of the lock separately.

The bottom a and top I) of the safe receive within their flanged edgesthe side plates, the back plate 0, and the door-frame e, and thescrew-bolt f connects these parts firmly together. Upon the door 9 isthe bolt h, sliding through the guide k, and provided with athumb-piece, I, that passes through the slot in the door g, and projectssufficiently to allow of the same being used in drawing the bolt back.The fence n at the inner end of the bolt h is contiguous to the circulartumblers r and s, and prevents said bolt being withdrawn except when thenotches 0f the tumblers are in position for receiving such fence. Thelever m and brake p apply friction to the tumblers, and the lever 0serves to project the bolt, both 0 and m being operated upon by thespring 1". are upon a stem, t, having a knob, 00, and dial c outside thedoor. Upon the tumblers r and s are the usual interlocking studs 3, tocause one to move the other; but uponthe tumbler s is a notched hub, 4,and a pin, 5, through the arbor' or stem t, enters these notches. Aspring, 6, serves to press the tumblers toward the pin 5. By thisarrangement the tumblers can be set around a quarter of a revolution tochange the permutation by simply pressing the tumblers away fromthe pin5, thus insuring a sufficient safety to the contents of the safe, andalso giving to children an alnusing and useful toy.

I claim as my invention- 1. The notched hub 4 on the tumbler s, and thepin 5 upon the shaft 13, in combination with the spring 6 and dial v,substantially as set forth.

2. The lever m and brake p for the circular tumblers r and s, and thelever o for the springbolt h, operated by one spring, 4", as set forth.

Signed by me this 11th day of March, A. D. 1874.
